i wonder what is "CR1X" file and "tdf" file?
how dose they make?
how can i open them?
CR1X is a human readable CRBasic code containing file for a CR1000X.
Use any text editor to read/edit it. For commands look into the Manual of the CR1000X or other help files.
More convenient for that Task is CRBasic which comes with PC400 or LoggerNet.
TDF is I think a table definition file.. but not sure.
